The Houston region SCCA is putting on a track event May 2nd-4th, and it includes a PDX on the 2nd. Link to registration.
If you don't know, PDX is what the SCCA calls an HPDE. Basically no passing in corners, or without a point by, and you normally have an instructor in the car with you. Cost is $150 for 7 20 minute sessions, which is a good deal. I am signed up and will be there unless I am offshore. Just wanted to give you guys a heads up, and drum up some more entrants because if these keep selling out, it might convince the region to run more PDX's along with their club races.
